Specification of Letters Patent.

Application filed November 13, 1912. Serial No. 731,191.

To all "IF/I01)? #312 (13 (701M011) Be it known that I, FRANK HINMA); PIER- rox'r, a citizen of the United States, residing at Sal't'ords, Horley, in the county of Surrey, England, have invented a certain new and useful Improvement in Type-Casting irlachines; and I do hereby declare the tolhiwing to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part ot' this specification, and to the figures and letters of reference marked thereon.

This invention relates to die or die-case pcsitioning or centering mechanism for type casting and composing machines of the class wherein a die-case or carrier is moved by the die-case positioning mechanism to position a selected die or matrix therein over a mold, after which the selected die or matrix is centered and clamped upon the mold for a cast to be made therefrom.

The matrices or characters in the die-case are arranged in rows running in two directions and the die-positioning movements of the die-case are effected by positioning or adjusting mechanism controlled by the gage pins, stops or their equivalent which are governed generally by a record strip or controller. and after the die case has been moved. to position a selected character or matrix over the mold, a centering pin engages the matrix, generally by entering an opening or cavity therein, and finely adjusts it and clamps it on the mold for the cast to be made.

The centering distance between matrices or characters in a standard or normal dieease has hitherto been constant and equal to or in proportionate relation to the distance between successive gage pins or stops, the distance between which has also been con stant.

YVith machines so equipped, various diecases each for a ditterent size of font may be employ-ed, but the constant distances between the gage pins of the positioning mechanism and the constant centering distance between matrices, places a limit upon the maximum size of the characters or font that can be produced, without involving considerable structural alterations in the machine, or the provision of a separate machine for separate sizes of "fonts.

liile a machine equipped withthe usual die-case positioning mechanism and with (lie-cases having matrices of normal dimensions or with normal centering distances meets general commercial requirements it is sometimes necessary or desirable to produce characters of abnormal dimensions or above a certain point size, and these cannot be dealt with in the ordinary machine, for the reason that the centering distances between the matrices can no longer be normal nor bear a constant relation throughout to the distance between the gage pins.

Matrices of abnormal size, having their centering distances a constant but difierent from the constant distance between the gage pins, can be centered over the mold, to be finely adjusted by the centering pin by the usual centering mechanism, and a mechanism for varying at each position the amount of movement to be imparted to the die-case as for example by the mechanism according to British Patent- No. 13209/09 (U. S. Patent 1,008,364, Nov. let, 1911) and, to a limited extent, abnormal matrices can be employed in a die-case so long as the centering cavity therein can occupy a posit-ion such that the centering distance between it and a neighboring matrix is normal in accordance with British Patent No. 20554/09 (U. S. Patent No. 980,959, Jan. 10, 1911) the die- "ase being positioned in this case, as with normal matrices.

It is the chief object of the present invention to increase the capacity of the machine and to provide for the positioning of a die-case or matrix carrier wherein the matrices are of abnormal dimensions and the centering distances are not normal, or wherein the centering distances are not constant throughout or throughout a particular row at matrices, at the same time permitting of the machine being employed with die-cases having normal matrices.

According to the present invention, the die-case, after it has been positioned by the usual positioning mechanism and released tlierelronn has an additional movement imparted to it by av supplementary mechanism. which finally positimis or moves the diecase bodily to position and finely adjusts the lccted matrix over the mold cavity.

The main or usua disease positioning mechanism i selective and the supplementary mcchantin moves the die-case to position the selected matrix.

In accordance with the present invention, there is provided on or opcratively connected with the diecasc or its carrier a. series of teeth. inclined surfaces. or devices having the equivalent e'li'ect with which a second or supplementary positioning member engages alter the die-case has been adjusted by the usual positioning ll'ltt'lltlillSlll to linally position the die-case and finely center. over the mold cavity, the selected matrix tor a cast to be ma dc.

Conveniently and preferably the inclined surfaces or teeth. are termed on or in a plate placed over the die-case. and the centering pin hitherto employed for finely adjusting or centerfng a selected H'lflilliX is made use of to impart the additional or final positioning movement to the die-case.

The teeth or the like are conveniently formed upon or carried by a plate situated on the top of the die- :asc and their inclined surilaces lead toward or into the centering cavities in the matrices so that the pin. a'ttcr engaging the said surfaces and moving the die caseienters a mat ix cavity and finely centers it and clamps it upon the molds.

The machine with which the present em.- bodiment of the invention is shown is that torming the subject matter oi": British Patentilo. 8633/95) Patent No. 625,998,1121) 30, 1895)) the die-case positioning mechanism being as improved by British Patent No. 9T476/03 (U. S. Patent No. 749,149. Januarv 19. 190 and the die-case as improved roe sees or modified in accordance with British Pat ent No. 4726/05 (U. 51 Patent No. 784,245, Mob. '7. 1905)v The die-case positioning mechanism. in the term in which it exists in the particular machine to which the present invention is shown applied and as described in the aforesaid specifications, comprises two sets of control mechanism operating on intersecting lines and each determining the position in one direction. Each set comprises a. primary controller consisting of a series of stop pins 1 (see Fig. 7) serially arranged; a primary positioning mechanism consisting of a pair of oppositely moving jaws attached to the outer ends of levers 3. which close upon the indicating stop pin; a secondary controller in the form of a bar provided with a stop (3 which stands between the said jaws and is brought to position thereby; a bolt 7 which is advanced to lock the secondary controller in position; and a secondary positioning mechanism in the form of aws connected to the outer ends of levers 1-1 5. which close upon the stop 6 and upon translating devices for the die-case A to bring the lattor to the position denoted by the stops (3. Each set of levers is connected to an actuator 11. 12, connected in turn to a prime mover 9 through spring boxes.

After the die case has been moved by the positioning mechanism above described it is released by the opening of the jaws carried by levers 41-. 5, and a die-centering pin E descends. entering a cavitv 7) (see Figs. and 6) in the end of the matrix B which has been roughly centered over the mold F and said centering pin finely and accurately centers the matrix over the mold cavity. holding it clamped on the mold until the asthas been made.

In these machines the character has a deli-- nitc position on the matrix and with relation to the mold, and the centering pin has a fixed position for dealing with all the matrices' 'l'. he matrices are provided with side grooves Z) for suspension on rods, bars or fingers b after the manner described in the specification of British Patent Xo. 4726/05 (U. .8. Patent No. 784E345).

In accordance with the present invention the die-case is provided with a series of inclined surfaces D with one or another o'l which in accordance with the adjusted position assumed by the die-case under the action or the usual die-case positioning mecha nism (l, 2, 3, at. 5, 6, 7, 9, 11, 12) the second or supplementary positioning member engages.

As above stated, the inclined surfaces D being situated over the die-case and leading into the centering cavities in the matrices. use is made of the existing centering pin E to constitute the second positioning memher. In descending, the pin E bears upon this surface D and shifts the die-case bodily so that it finally assumes a position to allow the pin to enter the centering cavity 72 in the matrix B situated in proximity to or under the particular inclined surface D which the pin engages.

In Figs. 1, 2 and 3, the centering cavities Z), in the matrices B (which are tapering or conical-see Figs. l and 6) are for the sake of clearness indicated by a circle representing the base of the cone.

In its final or ultimate stage of movement the pin E acts to center the particular matrix and clamp it upon the mold, as hitherto by seating in cavity 7). In order to permit and regulate this final movement the plate C, on which the inclined surfaces D are carried or are formed, is provided with circular holes or openings C (see Figs. r and 6) which extend from the lower surface of the plate immediately over the openings in the matrices B to the lower edge of the inclined surfaces D. Thus the pin E after moving the die case bodily, passes through the holes C and then into the cavity 7) of the selected matrix.

The inclined surfaces D are conveniently cut in the plate C and surround the holes C; in plan they appear for the particular font shown approximately circular as shown in Fig. l, and in sectional elevation they are conical, the sides in some cases being of unequal lengths and the angle varying (see Figs. &, 5 and 6) depending upon the amount of movement to be imparted to the die-case in each case by the pin E.

Taking a particular instance as existing in the present embodiment of the invention. when the normal positioning mechanism has acted upon the die-case, the latter is located with a particular matrix B (see Fig. 6) which represents that selected to be centered, over the mold so that the inclined surface at a point (Z directly under the centering pin E is approximately the point at which the pin will first engage. The pin then descends and, engaging the inclined surface D, by its continued descent moves the die-case laterally until the point 6? at the center of opening C is directly under the point of the pin E which latter by its continued forward movement finally enters the cavity Z) in the matrix and centers and :lamps it upon the mold.

In a die-case with normal matrices. the hitherto maximum number of matrices for characters up to 12 point has been arranged in 15 rows each containing 15 matrices (see F 3) corresponding with the serial arrangement of the fifteen pins 1.

In the font shown in the present example (Figs. 1. 2, T) the matrices are all abnormal 2 and are not all of the same size. Seven rows (counting from the left hand side in i Fig. 2) contain 15 matrices each and the remaining three rows contain 10 matrices each. The matrices in the first seven rows are no longer square as normal matrices are, but oblong. The centering distances between the matrices of any particular row of these seven are normal in one direction and therefore these matrices are centered over the mold in this direction of translation by one of the normal centering mechanisms. In the other direction the centering distances between these particular rows is not normal and therefore in this direction of translation the matrices are not positioned by the normal positioning mechanism alone, but by the normal positioning mechanism and in addition by supplementary mechanism E, D.

The matrices of the three remaining rows, Z. (2., the three right hand rows (see Fig. 2) are square but are of abnormal six. neither the centering distances between matrices of a row nor those between rows are normal; further. the centering cavities b are not central of the matrices. All the matrices of these rows require the positioning movements of the normal positioning mechanism and the supplementary mechanism E, D, to center them over the mold cavity, in both directions of translation.

In Fig. 1 the relative position of the pin E and the matrix after the die-case has been adjusted by the normal positioning mecha nism and after the supplementary mechanism has acted, is shown. The points X indicated at (1 represent the points at which the pin E will engage the surface D after the die-case has been positioned by the normal mechanism, and the point indicated by (Z represents the central point of the centering cavity of the matrix after the diecase has been moved by the pin E. The distance through which the die- "ase is moved in each case by the pin E is therefore the distance between the points X and -l in each case.

The present arrangement lends itself well to the requirements of the class of low quad mold operating mechanism, of which example are to he found in Patents No. 962,4:12. June 28. 1910. and No. 989,637, April 18. 1911. wherein the projection of the cut-oil member is indicated and effected by the presentation of a matrix with relatively shallow centering cavity whereby the centering pin is arrested at an earlier point in its seating stroke.

In the present instance said shallow seats :20. Fig. 1. may be formed in plate C at a point or points intermediate adjacent openings D t," and registering with one of the unused pins 1 of the centering mechanism. It will be seen that the pitch of the spacing devices of the supplemental positioning mechanism represented by inclines D and Qit associated perforations C differs from that of the selective positioning mechanism represented by step pins 1, and that the stations C of the supplemental positioning mechanism are controlled or designated by said stop pins. Thus in the machine illustrated each of the selective positioning mechanisms for effecting adjustments of the die case on. intersecting lines contains fifteen equally spaced pins 1 each designating a separate station in the direction of movement controlled thereby, while the supplemental positioning mechanism possesses but ten stations, counting from left to right in Fig. 1, and fifteen stations for seven rows reading from top to bottom of the drawing and ten stations for the remaining three rows.

By a proper selection of pins 1 of the two series the die case can be adjusted to bring the incline D of the desired station C in operative relation to the centering pin E, as indicated by the in their relation to the +s in Fig. 1. For example, the move ments of the die case from right to left in 1 to bring any one of the ten stations C of the supplemei'ital positioning mechanism in operative relation to the complemental engaging member represented by the centering pin will be performed successively by the first. third, fourth, sixth, seventh, ninth, tenth, twelfth, thirteenth and fif teenth stop pins 1, and in the case of the three right hand columns of station C the same numbered pins 1 of the other series will serve to designate successive stations; in other words the pins of the two selective positioning mechanisms designating stations i the two systems located and falling with in the area of the incline D adjacent any one of the perforations C may be employed to bring the selected perforation or station of the supplemental positioning mechanism in (lj'lQlZtiZl'VQ relation to the eomplemental engaging member or centering pin E, so that l l l l l l I. i l

upon the advance of the latter the die case 1 will be shifted from the station unheated by the selective positionlng devices to that indicated by the corresponding member of the supplemental. positioning mechai nism. it will be further noticed that the supplemei'ital positioning mechanism represented by plate C with its station designating openings C and directing inclines D for cooperation with the centering pin is responsive to the two selective positioning mechanisms when acting either singly or in conjunction, and operates to translate the station adjustments of the die case as measured or determined by the selective positioning mechanisms into those of the supplemental positioning mechanism, hence by a me substitution of die cases and without other change by way of addition or subtracprimarily l l l l l l r l l l r l l tion the spacing normal to the selective ponose-eve sitioning mechanism can be translated into that of the selected die case. That is to say by applying the supplemental positioning mechanism to the performing member, 2'. 0., the die case, whose position is determined b the conjoint action of the two signal controlled selective positioning mechanisms, the latter are utilized for designating the stations of the siu plcmentary positioning mechanism which are subsequently attained through the engagement of the plunger with th incline leading to the indicated station.
